Haptic interaction between two humans, for example, a physiotherapist assisting a patient regaining the ability to grasp a cup, likely facilitates motor skill acquisition. Haptic human-human interaction has been shown to enhance individual performance improvement in a tracking task with a visuomotor rotation perturbation. These results are remarkable given that haptically assisting or guiding an individual rarely benefits their individual improvement when the assistance is removed. We, therefore, replicated a study that reported that haptic interaction between humans was beneficial for individual improvement for tracking a target in a visuomotor rotation perturbation. In addition, we tested the effect of more interaction time and a stronger haptic coupling between the partners on individual improvement in the same task. We found no benefits of haptic interaction on individual improvement compared to individuals who practised the task alone, independent of interaction time or interaction strength.

触觉人与人的互动不会改善个体的视觉运动适应

两个人之间的触觉交互，例如，一名物理治疗师帮助患者恢复抓握杯子的能力，可能有助于运动技能的获得。触觉人与人的交互已被证明可以在具有视觉运动旋转扰动的跟踪任务中提高个人表现。这些结果是显着的，因为当移除帮助时，触觉上的帮助或引导个人很少有利于他们的个人进步。因此，我们复制了一项研究，该研究报告称人类之间的触觉交互有利于个体改进以跟踪视觉运动旋转扰动中的目标。此外，我们还测试了更多交互时间和伙伴之间更强的触觉耦合对同一任务中个人改进的影响。
